Preserves Jars consume less time than Kegs, but will usually yield less profit. However, low-value, high-yield crops like Blackberries, Green Beans and Corn are actually more profitable in the preserves jar than in the keg, as well as being much faster to process. As an example, corn juice, which is made in the keg, is worth 113g, but corn pickles, which are made in the preserves jar, are worth 150g. Salmonberry wine, which is made in the keg, is only worth 15g, but Salmonberry jelly, which is made in the preserves jar, is worth 60g.

Products

Quality of ingredients makes no difference to the finished product. The value of the finished product is determined using the base value (i.e., with no silver or gold star) of the fruit / vegetable. However, the preserved version is always more profitable than even gold star produce, although the profit margin is lower compared to normal produce.

Preserves Jar vs. Keg

The Preserves Jar increases the profit of a crop using the following equation: (2 × Base Crop Value + 50); while the Keg multiplies the base value of Fruits by 3, and Vegetables by 2.25. Because of this, low-value, high-yield crops like Corn or Tomatoes are more valuable in the preserves jar. The keg, on the other hand, favors crops with a much higher base value, such as Ancient Fruit or Melons. Below is a list of crops that are more beneficial to be put in the preserves jar.

It should be noted that these calculations ONLY involve the value gained in terms of max profit; if looking at profit per day based on the time required (2 days for the preserves jar, 7 days for the keg, plus aging time if desired), it is ALWAYS more beneficial to use a preserves jar, on the highest value item possible. Even starred crops do not approach the same amount of profit per day in a keg as in the preserves jar. See this reddit post for more details.

Notes

[1] Processing time calculates differently while sleeping than while awake. 1 hour = 60 minutes when awake but = 100 minutes when sleeping. So if you sleep a whole day, the machine would process 2400 minutes (100 × 24). If you work from 6:00AM till 12:00AM and sleep 6 hours, the machine will process 1680 minutes a day (60 × 18 + 100 × 6). If you work from 6:00AM till 2:00AM and faint 4 hours, the machine will process 1600 mins a day (60 × 20 + 100 × 4).

Trivia

The description of the Preserves Jar states that it makes Jam, but it actually produces Jelly.
